PHP 5.4 is not packaged on most Linux distributions so it may be easiest to install it from source. On Debian-based Linux systems, you can use the following commands to install PHP 5.4 in such a way that it won’t effect any other versions of PHP that you may have installed:
sudo apt-get install gcc libmysqlclient-dev libxml2-dev wget --trust-server-names http://us2.php.net/get/php-5.4.24.tar.bz2/from/us1.php.net/mirror tar xjf php-5.4.24.tar.bz2 cd php-5.4.24 ./configure --prefix=$PWD/installdir --enable-bcmath --with-mysql make install cd -
additionaly
--with-mysqli=mysqlnd --with-pdo-mysql=mysqlndphp-cgi
the binary used by the PHP SDK can be found in
php-5.4.24/installdir/bin/php-cgi
.
You can switch to the following folder, for the best pracice
/opt/php-5.4.24/installdir/bin/php-cgi
Then add to apache config file (/etc/apache2/http.conf)
ScriptAlias /php54-cgi /opt/php-5.4.24/installdir/bin/php-cgi/ Action application/x-httpd-php54 /php54-cgi
In desired virtual machine,
<VirtualHost> ... <FilesMatch "\.php"> SetHandler application/x-httpd-php54 </FilesMatch> </VirtualHost>
